# nansum

[common]\
fun [nansum](nansum.md)(input: [Tensor](../Tensor/index.md), dims: [LongArray](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long-array/index.html) = longArrayOf(), keepdim: [Boolean](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html) = false): [Tensor](../Tensor/index.md)

`nansum(input: Tensor, dims: LongArray = longArrayOf(), keepdim: Boolean = false)`: the `nansum` operator. Sum over `dims`, treating NaN entries as missing (contributing zero). Float dtypes only carry NaN; for integer inputs this is plain `sum`.
